BORE MECHANISM FOR EMIBROIDEBING-MAOHINES.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed February 21, 1907. Serial No. 858,736.

' Be it known that I, JOS PH A. Guonum', a

citizen of the United States, residing at New York c1ty,'in the county of New York and State of New York, have invented. new and useful Improvements in Bore Meclianism for Embroidering Machines, of which the fol- .lowing is a specification; My invention relates to boring mechanism for embroidering machines within which term I desire to include anynnd all mechfanism for perforating or plercing devices which will make holes in the fabric stretched upon the fabric frame of an embroidering ing mechanism machine.

It will be readily understood that the boris designed primarily to operate in conjunction with needle-mechanism to produce embroidery. The stitch forming mechanism is not shownin the drawings.

In the accompanying drawings, I have shown one specific form of apparatus having as its object to throw the bore points into tion with certainty in an indirect mane and to regulate their stroke without the necessity of. positioning the bore points as 1s done in the mechanism shown in U. S. Letters Patent No. 593,207, dated Nov. 9, 1897 and issued to The Kursheedt Manufacturing O6. as my assignee.

In these drawings :Figure 1 is a side elevation of one form of mechanism embodying my invention; Fig. 2 is an end elevation thereof; Fig. 3 is a side elevation of the ad uster hereinafter referred to with borer actuating rod dotted in Fig. 4 is a section thereof showing the borer actuating rod in full lines; Fig. 5 is a perspective view of a frame or lever 25 which, among other things serves the function of operating the adguster; Fig. 6 .is a side view of the actuating ever; 11, for the bore point actuating rod;

; Fig. 7 is a plan View thereof, partly broken away to show the bowl 16, and its moving pin 17 Fig. 8 is a perspective of an arm 21 which inserts the bowl 16 of the arm 11, into its cam; Fig. 9 is a face view of the cam 31 which rocks the frame 25; Fig. 10 is a side view of a fixed piece 37, for receiving the bowl and holding it stationary when the bowl is not in operation and holding it up to the work when the bowl is in operation.

In the drawing A indicates in general the frame of the embroidering machine forming the main support for the parts. The borers 1 are carried preferably upon a common bar 2 carried by the usual reciprocating rods or slides 3 working in bearings 4.. The rods 3 are pivoted to a bell crank-lever 5 pivoted at 6 on the frame of the machine. The lower or free end of the lever 5 is' pivotally connected to the upper end of the bore-point actuating rod 7 whose lower end is provided with a p1n 8 having a faceted or squared end 9, see Fig. 4..

The rounded portion 8 of the pin is adapted to enter a series of holes 10 in the arm 11 being located at the bottom of a counter-sink portion 12 so that the pin 8 will not leave the arm while it is being adjusted along the said rm as will be explained. The arm 11 is pivoted to the frame A at 13 and has at or nearits free end a sleeve 14 slotted at 15 (see Fig. 2) for a portion of its length and adapted to receive a bowl 16 having a pin 17 projecting therefrom through the slot 15 in the sleeve 14.

The bowl 16 is adapted to be entered at predetermined times into the cam slot 18 in the cam 19 carried on the shaft 20 supported from theframe of the machine; This moveidle swinging arm 21 is hung on the stud or support 22 and is provided at one end 23 .ment may be effected as follows; A normally with a cam slot 23 into which the pin 17 enters. The cam, slot 23 is open at 23 to allow the pin 17 to pass out of the slot. At its opposite end the arm 21 has a slot 24 forme by jaws 24' between which a pin is adapted to rest. Carried on the stud or sl 1pport is a'bent lever or frame 25 comprlslng an arm 26 having a slot 27 therein and an arm 28 having a bowl'or piece 29 working in a cam s 01; 30 and impartm to the arm or frame 25 a constant swmgl. dapted to cooperate with and enter te slots 24 and 27 in the arms 21 and 29 to con le them to swing together is a pin 32 adapte to enter locking apertures 33 n the main frame on its return stroke. The in 32 is moved and controlled by a jacquard or pattern connection 34 herein shown as actuated througzi a lever 35 by a lifter k of a series of 1i ers of thejacquard J clearl shown in my Letters Patent No. 528,632,. ma Nov. 6, 1894.

i In order to maintainthe bowl 16 in a normay provide a fixed locking and retaining piece 37 which is fast upon the stud or bar j ation. It also operates in a sense independ 22. Thislocking pieceis provided with a jaw- L ently of the positioning mechanism for the bounded recess 37 and an arm 37.

When 7 the bowl 16 is in its position of rest its outer g from swin ing movement. It is, however, free to sli e to leave the locking piece and enter the cam 18. It may, however, be found desirable to alter the extent of stroke of the borers. This may be done as follows: The holes 10 in the arm 11 are at different distances from the center of swing of the arm. By shifting the lower end of the rod 7 along the arm 11, and entering its pin 8 into any desired hole 10 the stroke of the borers may be varied without preliminarily positioning them for action. This may be accomplished by the adjusting mechanism which may be constructed as follows: A pin 38 is carried on the constantly movin arm 26 and is pivotally connected to a link 39 which is secured to or may be said to form part of the adjuster 40. This adjuster slides horizontally in response to the movement of the link 39 and is provided with a set of jaws 4.0 fitting over a guide stud 40 The adjuster is provided with a set of rigid teeth 40 and swinging end teeth 40 to prevent breakage upon any unusual accidental movement of the lower end of the rod 7. The rod 7 is provided with a stirrup 41 into which enters a plate 42 connected to a jacquard or pattern connection 43 extending to a jacquard or pattern element It. The pin 8 at the lower end of the rod T normally extends to the bottom of the recess 12 in the arm 11 and enters one of the holes 10 in said arm: Suppose it The jacis desired to shift it two holes.

uard goes into action and pulls the pin 8 rom its hole 10 (but not far enough to clear it of the recess 12) and enters its squared portion 9 into one of the spaces between the teeth 40 of the adjuster 40. This occurs during a pause in the reciprocation of the adjuster (see cam Fig. 9). moves forward one hole space and the pin is withdrawn by the jacquard and entered into the arm 11. The adjuster slides a step in the other direction and the pin is again entered therein and moved another step and entered into the proper hole in the arm 11. The jac uard connection 43 then remains idle unti the next adjustment'is to be effected.

The detailed operation will be understood from the fore oing description. It may be described as Follows: The adjusting apparatus may be put into action by the pattern mechanism several stitch periods in advance of the bore-point operating mechanism. This apparatus 0 erates in a sense independently of the ore-point moving mechanism by which for t e purposes of this case only I mean the mechanism for moving the rod '7 to bring about the boring oper- The adjuster k end is entered into the recess 37 and held 5 'inovement of the bore-points.

bore-point operating mechanism, by which for the purposes of this case only, I mean that. mechanism by which the bowl is entered into the cam without any positioning The jacquard forms the connecting link between these mechanisms in one sense and their direct connections with each other constitute connections in another sense so that they are at different times independent and interdependent. The positioning mechanism may now be thrown into action by the jacquard device coupling the levers 21 and 26 by the pin 32. This will by pin and slot connection, 17, 23* move the bowl 16 out of the slot 37* in the piece 37 and insert it into the cam slot 30 of the cam 31 by which it is moved to operate the borers. The rear end of the bowl 16 is kept up to its work, 2'. e. in the cam 31, by the arm 37 on the arm 37. The pin 32 is withdrawn by the jacquard and the boring continues until it is desired to stop the boring when the pin 32 is again engaged with the levers 21 and 526 when 21 is on its back stroke and the parts are restored to their normal positions.

In my present device the borers are normally in such a position that they may be operated without any change, that is to say they are simply advanced into the fabric and a primary positioning action is not necessary as is the case in my U. S. Patent No. 593207. By the present arrangement the jacquard positively connects the bore mechanism for immediate action and it remains in operation as long as desired without having to be positioned, during the operations. The jacquard, when the boring is completed, simply uncouples the bore mechanism and the bore mechanism remains where it is left. This coupling of the mechanism for immediate action is not effected by the change in the adjustment for advancing the operations of the borers.
